- Brief Summary
This study evaluates the efficacy and safety of the administration of betalactam antibiotics in prolonged infusion compared to intermittent infusion in children with sepsis. Half of participants will receive piperacillin/tazobactam, imipenem or meropenem in continuous or extended infusion, while the other half will receive piperacillin/tazobactam, imipenem or meropenem in intermittent infusion.
- Detailed Description
Sepsis is the leading cause of morbidity and mortality in hospitalised patients globally. Betalactams are time-dependent antibiotics, and so, the duration of time for which the free drug plasma concentration remains above the minimum inhibitory concentration (fT \> MIC) is the pharmacokinetic/pharmacodynamic index associated with bacterial killing and clinical improvement. Numerous studies have demonstrated that continuous infusion (infusion in 24 hours) and extended infusion (through prolonging the infusion time to greater than 3 hours) allows the maintenance of concentrations above the MIC for a longer period of time within the dosing interval (30 minute or 1 hour), and so, capitalises on the pharmacodynamic properties of betalactams and maximises bacterial killing, therefore potentially improving clinical outcomes. In adult patients, the several studies suggest that prolonged infusion may offer clinical benefits and significant reduction in mortality without increasing the risk of toxicity, however, there is limited information about these dosing strategies in pediatric patients.

Group Intervention Description Continuous Piperacillin/tazobactam Continuous Piperacillin/tazobactam Piperacillin/tazobactam initial doses 75mg/kg in 30 minutes infusion, immediately thereafter continue 300mg/kg/day, diluted in 5% glucose solution, at a concentration of 50mg/ml, to be administered in 24 hours infusion every 24 hours, as determined by antibiotic stability at room temperature. Intermittent Piperacillin/tazobactam Intermittent Piperacillin/tazobactam Piperacillin/tazobactam 300mg/kg/day, divided into 4 doses/day, diluted in 5% glucose solution, at a concentration of 50mg/ml, to be administered in 30 minutes infusion every 6 hours. Intermittent Imipenem Intermittent Imipenem Imipenem 80mg/kg/day, divided into 4 doses/day, diluted in 0.9% saline solution, at a concentration of 7mg/ml, to be administered in 60 minutes infusion every 6 hours. Intermittent Meropenem Intermittent Meropenem Meropenem 100mg/kg/day, divided into 3 doses/day, diluted in 0.9% saline solution, at a concentration of 7mg/ml, to be administered in 60 minutes every 8 hours. Extended Meropenem Extended Meropenem Meropenem initial doses 35mg/kg in 60 minutes infusion, immediately thereafter continue 100mg/kg/day, divided into 3 doses/day, diluted in 0.9% saline solution at a concentration of 7mg/ml, to be administered in 8 hours infusion every 8 hours, as determined by antibiotic stability at room temperature. Extended Imipenem Extended Imipenem Imipenem initial doses 20mg/kg in 60 minutes infusion, immediately thereafter continue 80mg/kg/day, divided into 4 doses/day, diluted in 0.9% saline solution, at a concentration of 7mg/ml, to be administered in 6 hours infusion every 6 hours, as determined by antibiotic stability at room temperature.
- Primary Outcome Measures
Name Time Method Number of Participants With Clinical Response Number of participants with clinical response at 14 days after antibiotic cessation, up to an average of 28 days or the day of your discharge if this occurred before 14 days after antibiotic cessation. Resolution. Disappearance of all signs and symptoms related to the infection.
Failure. Insufficient lessening of the signs and symptoms of infection to qualify as improvement, including death or indeterminate (no evaluation possible, for any reason).
- Secondary Outcome Measures
Name Time Method Number of Participants With Adverse Events Number of participants with adverse events evaluated by an physician at the time of administration of antibiotics, up to an average to 24 hours after the study drug cessation. Any harmful, undesirable, potentially serious and life threatening effects occurring during or after administration of the antibiotics proposed in this study (piperacillin / tazobactam, imipenem or meropenem), was evaluated as: none or adverse event classified according to the intensity of the clinical manifestation (severity) as: mild, moderate or severe and for each antibiotic.
